How can padding in CSS affect table spacing in PHP web development?

Padding in CSS can affect table spacing in PHP web development by adding extra space around the content within table cells. This can lead to uneven spacing and alignment issues within the table. To solve this problem, you can set the padding property to 0 for the table cells in your CSS stylesheet.

<style>
    table {
        border-collapse: collapse;
    }
    
    td {
        padding: 0;
    }
</style>

<table>
    <tr>
        <td>Cell 1</td>
        <td>Cell 2</td>
    </tr>
</table>
